Letters Patent No. 108,639, dated October 25, 1870.

IMPRovEM'EN-r in4 AwNlNes.

. To all whom it may concern..-

Be it known that we, Lows G. Seur and Gurus- 'rmN L. SCHURR, ofBaltimore, in the county of Baltimore and State of Maryland, haveinvented a. new and improved Awning; and we do hereby declare thcfollowing to be afull, clear, and exact description of the same,reference being had to the accompanying drawing making a part of thisspecitication, in which- Figure 1 is aside elevation,

Figure 2 a front elevation, and

Figure 3 a lateral vertical section of the ratchet, pawl, arm, cord, andspring, by the conjoint operation ot' which the awning is raised.

'This invention relates to that vclass of devices in which lazy-tongsare employed to raiseand lower an awning; and

'It consists-` First, in lazy-tongs placed at au inclination, inorderthat, after having been drawn together, they may, when released fromrestraint, extend themselves by their own gravity, andthus lower theawning.

Second, in an' arrangement of devices whereby the awning, after havingbeen lowered, may b e raised by winding a stud with a key, and, afterhaving been raised, may be lowered by releasing a pawl from a ratchet.

Referring tothe drawing- A is the end, and B the side of a house.

a aare metal bars tixed vertically to the side of the house, at adistance apart a trifle greater than the length of the awning, and insuch positions as to include between them the space to beprotectcd bythe awning.

b are the levers of two separate systems of lazytongs, which systems arejointed at one end to the bars 'a.- The maunervof such joiuting is this:the lower extremity of one of the two. end levers bof the system ispivoted in a slot -in -the bara, while the`upper extremity ot' the otherend level' b of the system is pivoted to the outer part ot' a link, c,the inne'r part of which enters a. slot in the bar b, above the otherslot above mentioned, and is jointed to the bar in said slot. The resultof this method of connection between the lzy-tongs and the levels b isthat the former hang at au inclination sufficient to cause them toextend themselves by their own gravity when the power that holdsthcmdrawn together is removed.

In the upper extremities of the two levels, b, at the outer ends of thetwo systems ot' lazy-tongs, a horizout-al rod, d, is secured, to whichrod the awning e` is made fast, and from which the'tlap f of the awningdepends. y

In lugs 7e, projecting horizontally from the side of the house,immediately above the bars a, a shaft, z',

I sition to the rst one,

vis loosely mounted, parallel with the rodd.- Around this shaft theawning is wound. v

A sheave, '11, is fixed on the shaft i, near one end of the same, aroundwhich sheave a cord, l, is wound. l

From thesheave'the cord l passes under a horizontal pulley, m, placedparallel with the side of the house, in a bracket that extends from thesame, immediately beneath the sheave lr.

A second pulley, n., similar in construction and pois secured to theside of the house, at about the same height as the pulley m, and at aninterval therefrom.

Over the pulley 'n the cord l is led, and thence ,vertically downward tothe drum e, on the. horizontal shaft p, that projects outward froma-bracket secured to the side ot' the house, and is inclosed in atubular case, 'r, in the rim of which is au orifice through which thecord l passes. On the shaft p is a ratchet, s, within the -case 1',

and to the side of the latter is pivoted a pawl, t, that is kept inconnection with the ratchet s bythe spring u. An arm, w, projects fromthe rear end of the pawl t out through a's'econd orifice in the case o'.

The awning, after having been let down, may be raised by applying a keyto the four-sided end of the shaft 1, that projects from the front ofthecaser,

and rotating said shaft iu the right direction for winding the cord uponthe drum o. This causes the shaft t to turn backward and t-ake up thelawning, retracting thc lazy-'tongs at .the same time. The paw-1 t holdsthe awning at any desired height. On depressing the arm 'w the pawl -isreleased from the ratchet, and this takes all restraint off from thelazy-tongs, and allows them to extend and lower the awning.

The above-described device for lowering and raising the awning may beplaced and worked inside the house as well as outside.

Having thus described ourinveution, What we claim as new, and desire tosecure by Letters Patent, is-

, 1. The combination ot' the lazy-tongs b, links e, and metalA bars a,constructed and operatingas and for the purpose specified. l 2. Thearrangement of the shaft i, sheave k,cord vI, pulleys m n, drum o, shaitp, ratchet s, pawlt, arm

lw, and case r, in the mannerand -for the purpose y specified.

Tile above specitication of our invention signed by us this 29th day ofSeptember', A. D. 1870. LOUIS G. SERT.
